A simple fix solved a big Camaro Z/28 tire problem

As far as problems with cars go, wheels slipping within tires due to an excess of braking, cornering, and accelerative forces is a pretty good one to have—way better than, say, a blown head gasket or dying window motor.

During performance testing of the Camaro Z/28, the engineers at Chevrolet sensed a vibration. Turns out the combination of Pirelli P Zero Trofeo R tires and Brembo carbon-ceramic brake rotors were causing the front wheels to slip within the tires under cornering and braking. The same thing was happening under acceleration on the rear axle due to the 505-hp 7.0-liter LS7's ridiculous thrust.

To prove the theory, the engineers marked the wheels and tires with chalk. They found that the wheels were rotating over 360 degrees within the tire over a single lap. Like we said, a cool problem, but less than optimal.

Their first solution was to use an abrasive paint along the wheel bead, but this didn't quite do the trick. Next they turned to media blasting, which provided a rough enough surface to prevent wheel slipping, and now the Z/28 is even better at doing things like this.

The Z/28 goes on sale this spring, and we should be getting a drive very soon. Until then, watch it do a 7:37 at the Nürburgring.
